The answer to the given question above would be FOUR. The number of copies of a DNA molecule that results from two replications of a single DNA molecule is FOUR. Since there are two replications, this makes the DNA molecule four. Hope this answers your question.
Hi!
The two types of endoplasmic reticulum are:
Rough Endoplasmic Reticulum RER
Smooth Endoplasmic Reticulum SER
The major difference between the two is the presence of ribosomes. The membrane of rough endoplasmic reticulum is bound by ribosomes, whereas the smooth endoplasmic reticulum is not bound by ribosomes.
Another difference lies in their function. RER is a storage house for proteins and is where the proteins are manufactured whereas SER is known for storing lipids and proteins both.

They were plants that preferred a warm temperature and couldn't survive in a cold one.
They discovered these plant fossils in Svalbard, Norway, which was once home to a forest. They were thought to have originated in a tropical jungle that was close to the equator. However, these fossils were discovered in the north, where the environment prevented their growth. This demonstrated that these trees were transported by continental drift to the northern, colder region that is now Norway.
